## Description

The SparkFun 7-Segment Serial Display combines a 4-digit 7-segment LED display with an ATmega328 microcontroller, allowing you to control every segment using just a few serial lines. It supports three communication interfaces — Serial TTL, SPI, and I²C — making it easy to integrate into a wide range of projects. The on-board ATmega328 comes pre-loaded with the Arduino bootloader, so the display can also be programmed for stand-alone operation via the FTDI header. Power and I²C pins are positioned on the sides of the board for daisy-chaining multiple displays, and mounting holes are included for secure installation. Key Features 4-Digit Blue 7-Segment Display – Alpha-numeric characters, numbers, and special symbols Three Serial Interfaces – TTL, SPI, and I²C Individual Segment Control – Control each segment, decimal point, apostrophe, and colon independently Adjustable Brightness – Selectable via serial command, saved to non-volatile memory Selectable Baud Rate – Also retained in non-volatile memory ATmega328 with Arduino Bootloader – Programmable for stand-alone operation Daisy-Chainable – Side-mounted power and I²C pins for multi-display setups Mounting Holes – For standoff mounting Specifications Display – 4-digit, 7-segment, blue LED Interfaces – Serial TTL, SPI, I²C Microcontroller – ATmega328 (Arduino bootloader) Dimensions – 41 × 23 mm (1.6" × 0.9") Package Contents 1× SparkFun 7-Segment Serial Display (Blue) Resources Schematic Datasheet Hookup Guide GitHub Repo
